IMPROVEMENT IN COTTON-GINNING MACHINE.

TO ALL WHOM IT MAY CONCERN: I I

Be it known that I, R. R. GWATHMEY,of the town of Middletown, in the county of Jefferson, in the State of Kentucky, have invented a" new and useful Improvement iii Cotton-Grinning hfachinesf' and I do hereby declare that thefollowing is a full andexact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1, plate 1, is a sectional longitudinal elevation of my cotton-ginning machine.

Figure 1, plate'2, is a plan view of the said machine.

The nature of my invention consists in the combination and use ofcertain devices, by means of which the cotton is easily fed, hull'ed, and ginnecl, thus saving time, using a. less power than for other ginning-machines now 1n use. I I

To enable others skilled in art to make and use my invention, I will now proceed to describe its construction and operation. I I

A A is the framework of my machine,and can be built of wood or metal, to suit convenience. G and C are two saw-cylinders, set parallel on the top of each other R R is a series of metallic (or Wooden) ribs,

setting. one'between each couple of saws, and form ng the top hoppers apron, E J, of my machine. Parallel to the axis oi cylinders P and P.-' E J, the upper apron, can he raiscdat will, and revolves around hinges, H G

cylinders and O are set two wire-cage cylinders, O and C, which revolve in the dircction sho'wn by arrows in red ink, (fig. 1, plate 1.) P- and P are two cylinders bearing brushes. Said cylinders set parallel to each other, and also to the saw-bearin ones C oud .C. Theouter brush-cylinder is of a larger diameter than the inside one. UK is a .c'onca-ve guideorbox under cylinder P, the upper edge of which concave is lower than to that ell'ect. When set down in proper position, it is held there by means of movable transverse bar B. A series of ribs, R R, Forms the hoppers apron or bottom, E J, between each couple Of:,\\lll(3h ribs the jaws r'cvolve.. This apron, E J, can be raised, withthe whole hopper ofmy machine, by means of hinges. L L is the lid'or cover of my machine, closing or opening at will, and to suit the purpose of the operator. In said lid is cut an opening coifresponding with the hopper. Lastly; S is a screw, by means of which the hulls are carried uway when discharged from top hopper-apron E J. B P is a pulley, set on stud or otherwise, and provided with the crank to which the proper motive=power is applied. A system of belts connects pulleys B P, B P, and B P together. Another system of bolts connects, also, pulleys a I), a b, a b", and a"b.' On the other side of my machine the necessary belts do connect pulleys O D, O D, d o D, nd lso 0 and 0.

The arrows in'rcd ink in fig. 1, plate 1, show, by the direction the pulleys should follow, how'thedifl'erent beltsabore mentioned must be set on. w I

My machine, now ready for use, and setin motion, if Idrop the cotton on to E J, the top saws will separate the hulls from the cotton without any injury to said cotton, and, prior to its entering into the gin proper,

will feed it uninjured, through ribs B, into the breast or hopper E J. As it reaches there, the lower saws, in

their rotary action, combined with that of. cn ;c-cylinders C and G, which very efl'ectually aid the roll, will entirely separate the cottoni'roni the seed without injuring the fibres; and the cotton thus far cleaned will be drawn through ribs R, and foil to brush-cylinders P and P, where it will receive the finishing touch, and come out entirely clean at aperture 0 T. v

In the above description of the construction of my machine, I have mentioned one upper and one lower breast-ribbed apron. The fig ire in additional drawirgtpla te 3) shows another mode of construction for the upper part of my machine. It consists, instead of using the said two ribbeda'prons, in dispensing with the upper one, to have the ribs of the lower apron longer, and to bend them so that the upper portion of each of them will set between two consecutive saws of the upper cylinder C, in the same manneras the same ribs respectively set between two consecutive saws of the lower' cylinder C. A ribbcd roller, RB, is set on top of and parallel with topsuw-cylindr C, with space enough between said roller and cylinder, so that the roller clearsthe saws of the cylinder. RE is connected by a belt with a. pulley on end of ribbed roller 0, andrevolves in the direction of arrow in red ink, marked on R B.' The pulley on-R 13 must be small enough to insure a very rapid rotary motion to said R. B. When thus constructed, I use my machine in the following way:

. I drop the cotton, hull and all, in its crude state, into the spacea r s, between roller R B and back of the machine. It thus falls on the ribs of the, apron back of R B. The saws, in their rotary motion inthe direction towards Z, hull said cotton, but the ribbed roller R B, revolving very rapidly in the direction contrary to that of the saw-cylinders, keeps the hulls and dirt back,,and the cotton and gin are alone fed to the breast of gin proper, where the operation continues, as has been above-described for two-apron machines.

I do reserve to use either of the'two above-described constructions.

In every one of the ginning or hailing-machines in which saw-cylinders are used, the bent of the points of teeth of the saws, as well astheir rotary motion, is always in an upward direction, viz,'towards the upper part or top of the machine, whereas, in my machine, the movement of the saws and'thc direction of the bent of their teeth are the reverse, that is, towards the bottom of my machine, (direction'shown by arrows in red ink, :u x.) i This reversed rotary movement of the saw-eylinders enables mexto hull and gin cotton with my one machine, at twodistinct places, but through one single and same operation. This is indeed one of the most importantvpoints of my machine. r

To enable others to understand still more fully the relative position of my ribbed aprons, saw-cylinders,

and direction of their rotation in my machines, I'would add that, if one imagines red-ink 'line Y to be a vertical line passing through the centre of my upper cylinder, and red-ink line Z astraight line' drawn from the foot or lower end of the breast or ribbed apron E J to the'centreof upper;saw-cylinder,'-the angle thus formed, and

having its vertex on the centre of said upper cylinder 0, will be about forty-five degrees; and the bent of the points'of the 'teeth of my saws", as well as the direction ,of the rotary movement of said saw-cylinders, will always be,.in my machines, the reverse of what it is in all other ginning-machines, viz, downwards towards letter Z, or the lower end of the lower apron. Y

When I use the second mode of construction for, the top of my machine, the screw-shovell'er S (Lia-hove described as designed to carry away or discharge the hulls and dirt separated from the cotton in the upper breast or hopper-apron E 3', stilleil'ects the same operation when said apron is suppressed and replaced by the:

second mode of construction. p l

Having thus described my invention, what I claim as my invention, and desire to secure by LettersPatent of the United States, is-'- 1. The mode oi hulling and ginning cotton into one same machine, and at one same operation, by-means offone, two, or more, ribbed aprons, combined with one, two, ormore, saw-cylinders, invariably driven or rotated in the'direetion shown er red-ink arrows a: 2:, fi s., lates 1 and 3, in the manner and for the at 05c above P g P P P 'set forth and described.

2. The combination of wire-cage cylinders C C" with saw-cylinders Q and C and ribbed aprons E J and E J, the whole constructed and operated in the manner and for they purpose above set forth and described.

-3. The combination ofribbed cylinder R B (plate 3) with top saw-cylinder C, and ribbed apron E J, and

- shoveller-screw S C, the whole constructed and-operated fortheqaurpose and in the manner above set forth and vhulled and rid of all'dirt and trash, in the manner above set forth and described.
